Per my action item from the FtF, I am revising the proposal to address
Issue 161.
Issue 161 concerns section 11.1 of the CSS 2.1 spec
(http://www.w3.org/TR/CSS21/visufx.html). Specifically, the line "A
descendant box is positioned absolutely, partly outside the box. Such
boxes are not always clipped by the overflow property on their
ancestors." has been cited as being confusing, as it may imply that
absolutely positioned elements (those with position:absolute or
position:fixed) don't ever get clipped by an overflow:hidden ancestor.
My proposed change is to replace that line with:
"A descendant box is positioned absolutely, partly outside the box.
Such boxes are not always clipped by the overflow property on their
ancestors; specifically, they are not clipped by the overflow of any
ancestor between themselves and their nearest positioned ancestor."
